Definitely not the best but at this moment I bring...

Divine Avenger, Leviathan, Polaris, Blitz Needle, Vog Cub Cap, Vog Cub Coat, Grey Owlite Shield, 2 Elite Sword Focus Module
any kind of UVs are just extra bonus.

I like VH ASI + Max CTR on sword because I often charge divine avenger near Slag Walkers.
ASI helps avoiding their "slap" attack when I release charge.
Divine Avenger + Polaris could destroy all wheels from any angle.
Blitz Needle Charge Attack is a killer for trojan and vanaduke. I switch my gun to polaris if my party messed up on vanaduke a lot.
Shock could stop vanaduke's rotating/dashing for a second.
I found that grey owlite shield is much better than any shield. I never worry about shadow attack since it's melee and you just need to stay in distance but I always run into shadow fire (on floor) and vanaduke's orbs + mask which deals elemental damage.
Leviathan is mostly for Vanaduke phase 1 and mask phases.

Full Vog - Elemental defense is major in FSC, Zombies are too easy to avoid
Volcanic Plate Shield/Grey Owlite Shield - VPS for Vana, GOS for FSC (excluding Vana)
Divine Avenger - Elemental Damage
Cold Iron Vanquisher/Barb Thorn Blade - CIV for the Vana mask, BTB for Trojans and Vana, BTB charge can hit vana through two layers of fireball.
Shivermist Buster - for freezing everything you see in FSC
Polaris/Blitz Needle - Polaris for Zombies and a little bit for Vana, Blitz for Trojans and Vana

Rangerwill, doesn't Armor of the Fallen penalize your damage against fiends, including trojans?

Dirt, you're right of course that he ends up with Bonus Fiend Medium. I guess I was expecting more, from how he was talking. But medium isn't bad. :)

Divine Avenger-CTR VH, ASI VH
Argent Peacemaker-ASI VH, Undead VH, Fiend VH
Fang of Vog-ASI VH, CTR VH
If I solo, Nitronome CTR VH, undead VH. If not, Dread Venom Striker ASI VH, CTR VH

Trinkets

True Love Locket x2 OR Anti Lag Trinkets (5*)x2

Currently I'm playing FSC with Ancient plate set and all sorts of weapons to be leveled, but I always carry Divine Avenger and argent Peacemaker with me.

If I were just to beat FSC and Duke, I'd go with this (no special UVs, I hate UV hunting):
- Vog Set
- Grey Owlite Shield (Fire)
- Divine Avenger (Zombs)
- Argent Peacemaker (Zombs and Vana)
- Barbarous Thorn Blade (Trojans)
- Dread Venom Striker (Turrets, Vana 1st phase, Vana mask phase)
- CTR focus (for DA charge)
- DMG focus (just because) or Heart Pendant

The Thorn blade could be interchanged with this electron vortex bomb to collect the zombs and slay them with DA afterwards. Or leave it away and use the remaining slot for leveling items.

I would go for:
Full Vog (Half vog and half skolver is good too)
Volcanic Plate Shield (It has saved me plenty of times)
Divine Avenger
Shivermist Buster
Blitz Needle (Maybe switch out for my levi)
Polaris

Slash Module Mk 2 (I think that's what it's called)
Bomb Module Mk 2/ Gun Module

What I use now:

Leviathan Blade CTR med
Shivermist Buster CTR med
Polaris
-a weapon to be heat up-

Vog Cub Cap
Divine Mantle UV shock high

Grey Owlite Shield

Elite Sword Focus
Elite Bomb Focus

What I would use:

Leviathan Blade CTR med
Shivermist Buster CTR med
Polaris dmg vs Undead: VH
-a weapon to be heat up-

Vog Cub Cap UV Normal def Maximum
Divine Mantle UV shock res Maximum

Grey Owlite Shield UV shadow def Maximum

Elite Sword Focus
Elite Bomb Focus

Chaos Cowl - High Fire Resist
Nameless Pocho

Wep 1: Leviathan - Low undead + low slimes + Vh ASI
or
Divine Avenger - Med CTR

Wep 2: Hail Driver - High CTR
Wep 3: Polaris - Low Gremlin right now >.>
Wep 4: Blitz Needle - Medium CTR

Shield: Swiftstrike Buckler - Med Shadow

Trinket 1: Charge Medium Gun
Trinket 2: Damage Medium Gun

my loadout has been:

Divine Veil with a small UV somewhere, I think it's Shadow
Volcanic Demo suit, UV normal low
Owlite Shield
DA
Polaris
Blitz Needle
Voltaic Tempest
Trueshot module
Tri-heart pendant.

I tried being group bomber, but I'm no good at keeping Vanaduke frozen. I'm going to probably abandon bombing down there in favor of 2 guns and 2 swords, as I have an ASI high CIV too. I suck at Shivermisting, and Nitronome and Voltaic Tempest lags the game. I think in the future, I'll make my setup 2 elte trueshots, or get a shootist piece of armor. There's no way I'm going down to Vanaduke without my Blitz Needle now.

Also, I just finished up an Ironmight shield, and a Volcanic is on the way.

@evilduck

you bring the FOV down into a Vanaduke run? It's a nice elemental sword, but I wouldn't have thought it'd be super-useful down there. It's a must-have on my JK runs now. heheh

@Dragonist

ooh ya, I love FoV. I've been soloing JK with it. I also have a Blitz Needle which works arguably better on Trojans, IMO at least.

I tend to use:
Volcanic plate mail
Glacius line
Vog Cap
Grey Owlite/ Barbarous thorn shield
and either my silversix or Dark thorn blade

I think this thread will be better if we put our own set (since obtaining 3 max uvs on one item is near to impossible)

I'll start with my "For Vanaduke" loadout:
- Vog Cub Cap (Max Shadow)
- Vog Cub Coat (Max Shadow)
- Grey Owlite Shield (Max Shadow)
- Divine Avenger (CTR VH)
- Shivermist Buster (CTR VH)
- Polaris (CTR VH) [only used for the wheels]
- Blitz Needle (CTR VH) [for them horses]
- Elite Slash Module x2

Some replacements:
- Swiftstrike Buckler (Max Piercing) [for shield, obviously]
- Crest o' Almire (High Elemental) [again, for shield]
- Voltaic Tempest (CTR Med) [replacing Polaris]
- Skolver Coat (Normal High) [for armor, obviously]
